Dual Boot openSUSE Leap 42.2 and Windows 10 on an Acer Aspire V15 Nitro Black Edition

I got a brand new Acer Aspire V15 Nitro Black Edition. After playing around a couple of minutes with the preinstalled MS Windows 10 Home there was pretty soon an urgent need of getting LINUX up and running on it. I like to have a Dual Boot machine in case there is any need to startup Windows again later e.g. to compare battery life time etc..

Because the Nitro doesn’t have a internal DVD drive and the ordered USB-DVD drive was not delivered at that point, I prepared a USB-Stick with the current openSUSE Leap 42.2 with my Desktop openSUSE 42.1 machine.

After plugging the stick into the Nitro and doing the first reboot, I recognized that there is no BIOS anymore but UEFI an there is offered no option to press a key to choose the boot device. A quick internet search gave me the tip to go to the Win10 system settings > Recovery options > … That lead me to the UEFI replacement of the former BIOS GUI where I could turn on the F12 key for the boot menu and change the order of the boot devices.

With the next reboot I could manage to do the openSUSE install process. During the partition step I was remembered to mount the existing boot partition /dev/sda1 to /boot/efi. But after first reboot the system was going directly to Windows again. Some more internet search lead me to the tip to make a new boot manager entry with the following Windows command (startup an cmd as Administrator):

bcdedit /set {bootmgr} path \EFI\opensuse\shim.efi

This supports the still activated SecureBoot. And next reboot successfully shows the boot menu for the two installed OS.
